This is a creamy, flavorful, and incredibly healthy soup. The next time you're in the mood for split pea soup (also very healthy), try this instead. It has a wonderful body and a great hearty flavor. If you haven't had sumac before as a seasoning, this is a great dish to try it with. Sumac is commonly used in the middle east to season just about any dish, and it's great over this soup. Put a few sprinkles of sumac and cayenne over this soup and it takes on a rich and spicy demeanor. Between the broccoli and the lentils, this soup packs an amazing amount of nutrients and protein in a delicious package.
